Answer:

Lessons has Lindsey finished = 21

Step-by-step explanation:

It is given that,

Joe has finished 14 of the 30 lessons in his piano book. Lindsey has finished the same percent of lessons from her piano book, but her book contains 45 lessons.

<u>To find the percentage of lessons of Joe</u>

Percentage = (14*100)/30 = 140*3 = 46.67%

<u>To find the lessons has Lindsey finished</u>

Lindsey has finished the  46.67% of lessons from her piano book

46.67% of 45 = (46.67*45)/100 = 2100/100 = 21

Therefore lessons has Lindsey finished = 21

seropon [69]

Answer:

see below

Step-by-step explanation:

f(x) = –(x + 6)(x + 2)

The function is increasing until it reaches the vertex, so it will increase until x=-4.  The function will decrease after the vertex, so after x = -4

increasing: -∞ < x < -4

decreasing : -4 < x < ∞
